Download file to see previous pages Several concepts of force have formed part of statics and dynamics since ancient times. Ancient contributions to statics ended in the work of Archimedes in the 3rd century BC, and even today it is a part of modern-day physics. On the contrary, Aristotle's dynamics included intuitive misunderstandings of the function of force which were in due course-corrected in the 17th century and ended in the work of Isaac Newton.

After the developments in the field of quantum mechanics, the knowledge has found out that each and every particle influence each another through fundamental interactions and consequently the standard model of particle physics demands that everything experienced basically as a "force" is actually mediated by gauge bosons. In particle physics, gauge bosons are bosonic particles that play the role of carriers of the fundamental forces of Nature. And these fundamental forces can be classified as strong, electromagnetic, weak, and gravitational (Young and Freedman). As mentioned earlier forces can be directly perceived as a push or pull, this can provide an instinctive framework for describing forces. The intuitive notion of force is quantified using operational definitions that are consistent with direct perception but are more precise. The SI unit for force is the Newton, which is defined by Newton = kg m/s2 as may be seen from Newton's second law (Nave n.pag).

Isaac Newton was the first person who argued explicitly that, generally, a constant force causes a constant rate of change (time derivative) of momentum. In fact, he gave the first and the only mathematical definition of the quantity force. He defined force with the following formula:

Newton explains that force is the time-derivative of momentum. Later Newton went on to publish his Principia Mathematica which used concepts of inertia, force, and conservation to explain the motion of all objects (Young and Freedman). ...Download file to see next pagesRead More

### Strong vs Weak Matrix Structure

...? PROJECT MANAGEMENT Strong vs Weak Matrix Structure The literature indicates that weak matrix organizations are no less than a nightmare for project managers. This is true because although, they have the authority and power to make plans, divide the project strategy and even closely monitor the execution as well, project managers do not have any real authority over the project team members, most of whom remain reliant on their functional managers for provision and use of resources. Therefore, in these organizations, technically the project managers do not remain “managers” in the truest sense but their role is reduced to that of project “facilitators” (Gottlieb, p. 109). Project managers within a weak matrix organization often fail...

### Strong and weak states

Current paper focuses on the presentation and the explanation of the differences between strong and weak states – as these differences are highlighted in the relevant literature. Emphasis is given on both the characteristics of strong and weak states and the reasons for the existing differences between the above types of states. The understanding of the criteria and the reasons for the categorization of states to strong and weak could help to explain the format of relationships among states in the context of international community. More specifically, strong states are most likely to show their power in influencing key international policies by intervening in the political, social and economic decisions of the weak states (Nelson...

### Definition

...?Definition The term “frenemy” refers to a person who is considered to be both a friend and an enemy. The term itself is a result of combining the words ‘friend’ and ‘enemy’. An example of a frenemy is someone who plays both the roles of a friend and enemy in regard to an individual friendship. In essence, there is a love and hate relationship between the two people (Voo, 2007); one moment, they are getting along just as friends should, but the next moment the two friends find themselves against each other. A frenemy is often treated accordingly, with everyone being conscious of what that person is. Another type of frenemy is a person who is considered to be a friend but is constantly putting others in their group down. It is the type...

### Weak Form Market Efficiency

However finance theory assumes idealistic models for the stock markets and formulates the investor utility functions and expectations accordingly. These models are based on perfect competition and passage of information in an unfettered manner. As Wikipedia (2007) seems to point out, "In economics and financial theory, analysts use random walk techniques to model behavior of asset prices, in particular share prices on stock markets, currency exchange rates and commodity prices. This practice has its basis in the presumption that investors act rationally and without bias, and that at any moment they estimate the value of an asset based on future expectations. Under these conditions, all existing information affects the price, whic...

### Strong versus weak advertising theory

A case in point is Andrew Ehrenberg who advanced a controversial treatise in 1974 about how advertising works. He challenged the assumption that advertising has the capacity to change attitudes unaided, and suggested that it normally worked by strengthening beliefs shaped from what are usually high level of consumer experience and awareness (Heath 2006). The argument of Ehrenberg was concentrated on the prevalent theory that advertising was a strong kind of persuasion, and his assumption became widely accepted among advertising agencies (Agres, Edell & Dubitsky 1990). However, it is important to take into consideration the fact that it was a period when the sales impacts of advertising were viewed by many as lasting, difficult to...

### The Relative Merits of Weak and Strong Advertising Theories

...﻿The Relative Merits of Weak and Strong Advertising Theories As the use of advertising has become more and more integral to the success of businesses, approaches to advertising have become increasingly sophisticated. Despite decades of research, though, the debate continues to rage regarding the relative merits of strong or weak advertising. According to the strong theory of advertising, advertising works through a process of conversion whereas the weak theory suggests that it works through a process of reinforcement. A basic understanding of these theories can be deepened through application of associated advertising models such as the ELM model or the ATR model respectively. The ELM model is a model of persuasion demonstrates how...
